DISPENSING INK-BOTTLE.

Specification of Letters Patent. Patented Aug, 13, 1918,

Application filedJanuary 12, 1918. Serial No. 211,569.

i To all whom it may concern Be it knownthat I, GEORGE SoHRoDER, a citizen of the United States, residin at Berkeley, in the county of Alameda, tate of California, have invented a new and useful Dispensing Ink-Bottle; and I do hereby declare the following to a full, clear, and exact description'of the invention, such. as willenable others skilled in the art to which i appertains to make and use the same.

The present invention relates to av dispensing bottle for the packaging of ink and like fluids, the object of the invention being toprovide a bottle of this character which embodies novel features of construction whereby the ink will feed as required from the main compartment to a comparatively small dipping well, thereby enabling the ink to be used without waste or excessive evaporation.

Further objects. of the invention are to provide a dispensing ink bottle which is comparatively simple and inexpensive in its construction, which can be used for bottling ink for the retail trade, which can be easily packed for shipment, and which will enable the ink to be used without the customary loss by waste.

With these and other objects in-view, the invention consists in certain novel combinations and'arrangements of the parts as will more fully appear as. the. description proceeds, the novel features thereof being pointedout inthe appended claims.

For a full understanding of the invention, reference is to be hadto the following description and accompanying drawings, in which: I .7

Figure 1 is a top plan view of a dispensing ink bottle. constructed iii accordance with the. invention.

Fig. 2 is an enlarged vertical. sectional view throughthe bottle on the line 22 of Fig. 1.

Fig. 3 is a transverse vertical sectional view on the line 33 of Fig. 2."

Fig. 4 is a front elevation of a portion of the bottle, showing the upstanding flange which extends around the mouth of the dipping well.

Fig. 5 is a bottom plan view of the tubular shell which is fitted in the mouth of the clipping well.

Fig. 6 is a top plan view on a reduced scale, showing a modified form of the invention,

7 Corresponding and like parts are referred to in the following description and indi cated in all the views of the drawings by the same reference characters.

Referring to the drawings, which illustrate one embodiment of the invention, the numeral 1 designates the main compartment of the bottle, and 2 a shallow and comparatively small dipping well which is arranged at the front of the main compartment and preferably has the walls thereof integral with the walls of the main compartment. The bottle may be made rectangular in, shape, so as to be easily and economically packed for shipment or storage, and the top of the main compartment has the forward side thereof inclined downwardly to the top of the dipping well, as indicated at 1. A filling opening is provided in the top of the main compartment, said openingbeing surrounded by a downwardly projecting flange 3 and being: designed to be closed by a cork 4. A layer of wax 5 or other similar material may be superposed upon the cork 4 for the purpose of providing a substantially air-tight closure, since this is essential to the proper working of the bottle. A partition 6 sepantes the main compartment 1 from the dipping well 2, sai d partition being formed with a small opening or narrow vertical slit 7 which extends from the bottom of the bottle to a point spaced from the top of the dipping well. When the bottle rests upon the base thereof and is in a substantially horizontal position the ink or writing fluid from-the main compartment 1 will flow into the dippingwell 2 until the level of the ink reaches the top of the slit 7. The slit 7 will then be closed by a liquid seal rendering it impossible for air to enter the main compartment 1 to displace any ink which might flow therefrom into the dipping well. The level of the ink in the dipping well will then be maintained automatically at this level, since ink will flow from the main com partment into the dipping well just as rapidly as it is used from the dipping well, a constant level of ink being maintained in the dipping well at all times.

In order to reduce evaporation of the ink to a minimum, a tubular or cylindrical shell 8 is fitted in the opening of the dipping well,

" said shell being of a suflicient length to exribs 10 on opposite sides thereof, and the upper end of the shell 8 is returned at S and provided at opposite sides with Wings 11 adapted to be rotated under the inclined ribs 10 of the flange 9 to seat the shell firmly in position. A rubber washer 12 may be interposed between the upper edge of the flange 9 and the returned portion 8 of the shell 8 to provide a tight joint between the memhere. The only portion of the ink which is exposed to surface evaporation is that within the shell 8, and loss and deterioration by evaporation is thus reduced to a minimiun. A stopper 13 is fitted removably within the upper end of the shell 8, being shown as provided with a head 1% for convenience in handling and manipulating the same. This head might be covered in the usual manner with sheet metal, and might initially be provided upon opposite sides thereof with depending hooked arms 15 adapted to engage the returned upper edge 8 of the shell 8 to prevent accidental loosening or removal of the stopper. There would then be no danger of the stopper coming loose during shipment or while the bottle was being handled. The ultimate purchaser of the bottle could bend the hooked arms 15 into inoperative position or break them away from the head of the stopper. -With this bottle it will be obvious that the ink will be fed as required from the main compartment 1 to the dipping well 2, thereby preventing waste, and that excessive evaporation will be prevented by the shell 8.

Fig, 6 illustrates a slight modification of the invention, in which the bottle has a different shape, being tapered in width toward the forward end thereof so that the clipping well is comparatively narrow. The main compartment 1 is formed substantially as previously described, the forward portion of the top of the main compartment being inclined downwardly at 1. The dipping well 2 is narrower than the main compartment 1 which has the forward portion thereof tapered, as indicated. In all other respects the construction and operation of the dispensing bottle are exactly as previousy described. The dipping well is designed to hold just a suflicient quantity of ink so that when the pen is dipped therein it will receive exactly the proper amount of ink, neither "too much nor too little, and there will be no danger of the fingers being soiled. The bottles may be made in different sizes, suitable Copies of this patent may be obtained for for domestic use, office use, or school use, and they will result in a great saving of time, since the pen can be dipped instantly without any hesitation, and exactly the proper amount of ink will remain in the pen when it is withdrawn from the well.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1. A dispensing ink bottle including a sealed main compartment and a comparatively small dipping well arranged at one side of the main compartment and having a mouth at the top thereof, said mouth being surrounded by an upstanding flange provided with laterally projecting short cam ribs, a tubular shell fitted in the mouth of the dipping well and extending downwardly to a point normally below the surface of the liquid therein, the upper end of the tubular shell being returned and provided with hooked lugs adapted to be rotated into a locking engagement with the before mentioned cam ribs of the flange, a stopper fitted in the upper end of the tubularshell, and locking means carried by the stopper for detachably engaging the tubular shell to hold the stopper in position.

2. A dispensing ink bottle including a sealed main compartment and a comparatively small dipping well arranged at one side of the main compartment and having a mouth at the top thereof, said mouth being surrounded by an upstanding flange provided with laterally projecting short cam ribs, a tubular shell fitted in the mouth of the dipping well and extending downwardly to a point normally below the surface of the liquid therein, the upper end of the tubular shell being returned and pro-vided with hooked lugs adapted to be rotated into a locking engagement with the short cam ribs of the flange, a stopper fitted in the upper end of the tubular shell, and hooked arms carried by the stopper for detachably engaging the returned upper end of the tubular shell and to hold the stopper against displacement.

In testimony whereof I have signed name to this specification in the presence of two subscribing witnesses.

GEORGE SCHRODER.
